Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516212, here are decompositions:
- 11 + 31516201 = 31516212
- 23 + 31516189 = 31516212
- 29 + 31516183 = 31516212
- 53 + 31516159 = 31516212
- 59 + 31516153 = 31516212
- 73 + 31516139 = 31516212
- 83 + 31516129 = 31516212
- 89 + 31516123 = 31516212
Showing the first eight; more decompositions exist.
